Jack the vehicle up so the rear suspension is hanging, get a can of HD silicone spray, and soak the bushings really good. Then, grease in between each leaf in the pack, mostly at the ends of each leaf where the most pressure is. you may need to pry the leafs apart just a bit to get the grease in there.

Did the same thing when mine were squeaking. It has been about a month or so since I did and I haven't had a squeak since.
